SASH-LOCK.

Application filed January 21, 1911.

T 0 all whom it may concern:

Be it known that I, (humans A. HUNT, a citizen of the United States,residing at Newburgh, in the county of Orange and State of New York,have invented new and useful Improvements in Sash-Locks, of which thefollowing is a specification.

This invention relates to sash fasteners and its object is to providemoving members sliding on each other and having flanges which look theplates between the sash and the frame molding to prevent the sash frombeing moved. In order to accomplish this resultcertain effectual andsubstantial means are used which are capable of being adjusted toaccommodate the device to any size window as will be more fullydescribed in the following specification, set forth in the claims andillustrated in the drawings, wherein,

Figure 1 is a perspective view showing the device applied to a window.Fig. 2 is a face view of the fastener. Fig. 8 is a rear view. Fig. 1 isa plan view.

Applicant is aware that sliding plates have been used to effect thelocking of window sashes to prevent the movement of same, but the meansheretofore adapted to separate the plates has been such thatinsuflicient power has been produced to accomplish this result.

In the present invention, two plates 10 and 11 are used, each havingserrated or rasp faced flanges 12 and 18 at opposite ends to each other,the flange 18 being adapted to fit against the sash 1 1, while theflange 12 abuts against the strip 16. When, therefore, these two platesare separated, a pressure is exerted on the sash 1 1 so as to preventits movement up or down, the roughened faces offering sufiicientfriction toprevent the sash from moving.

The separation of the plates is effected by means of the screw 17playing in the projection 18 from the plate 10 which passes through aslot 19 in plate 11, while the other end of the screw works in a bracket20 pro- Specification of Letters Patent.

jecting from the plate 11 and formed from that portion of the sheetmetal which is cut from the slot 19.

As will be seen in Fig. 3, the rear side of the fastener is providedwith a slotted extension adjuster 21 pivoted at 21 and passing throughone of the slots is the screw 22 which is a stem from the projection 18,and by which the projection is locked to the adjuster 21. The screw maybe transferred to any of the slots 23 of the extension 21 so that theplates may be separated to a greater or less degree to locate the devicein window frames of various sizes.

The bracket 20 may be constructed of thicknesses of sheet metal bent soas to inclose a nut 24, or the said bracket can be constructed toconstitute a projection such as 18, fastened to the plate 11. When itdesired, a screw 25, such as is shown in Fig. 4, may be employed, thesaid screw being threaded in one direction only and swiveled to thebracket 18 by means of pins 26, this screw being preferably used inplace of the one heretofore mentioned. The screws 17 and 25 may also beoperated by a key or a permanent crank arm may be secured to the same torelatively adjust the plates.

The projections or threaded brackets 18 and 20 may be formed from thatportion of sheet metal which is cut from slot 19 and slot of plate 10and used without an extension, the proper separation of the plates being efiected by means of screw 17 threaded right and left.

It is obvious that modifications may be adopted which are capable ofadjustment without departing from the essential features above describedand yet be confined within the scope of the appended claims.

What I claim as new and desire to secure by Letters Patent is,-

1. In a sash lock, the combination with separable plates having serratedflanges, of a slotted adjusting plate at the inner side of the lock, astud carried by the adjustable plate, a bracket 0n the outer plate andsepanut, and a screw playing in the bracket and 10 rating means carriedby the stud and operatthe bearing to separate the sliding plates. ing onthe bracket.
